HOISTING APPARATUS AND TRANSPORTING- MEANS THEREFOR.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed December 5. 1906. Serial No. 346,493.

To all whom it may concern:

Be it known that I, FREDERICK SANDWISCH, a citizen of the United States, residing at Woodville, in the county. of Sandusky and State of Ohio, have invented a new and useful Hoisting Apparatus and Transporting Means Therefor, of which the following is a specification.

This invention relates more particularly to derricks for use in the oil fields and similar places where pip ing, pumps, and the like have to be raised from the wells or holes in the earth.

The principal object of the present invention is to provide novel apparatus of a comparatively simple character that can be transported from place to place, properly positioned with ease and expedition, raised to operative condition, and constitutes strong, durable and effective means for elevating purposes of the character above outlined.

The preferred form of construction is shown in the accompanying drawings, wherein Figure 1 is a side elevation of the apparatus when in condition for transportation. Fig. 2 is a view in elevation, showing the derrick when being placed in position. Fig. 3 is a top plan view of the turntable. Fig. 4 is a vertical sectional view therethrough. Fig. 5 is a cross sectional view. Fig. 6 is a view in elevation of the derrick when set up. Fig. 7 is a vertical sec- J tional view therethrough. Fig. 8 is a cross sectional view on the line 88 of Fig. 7. Fig. 9 is a section on the line 99 of Fig. 7. Fig. 10 is a sectional view on the line l0-l0 of Fig. 9. Fig ll is a sectional view on an enlarged scale on the line 1111 of Fig. 7. Fig. 12 is an end elevation of the lower portion of the derrick, with the handle crank broken off. Fig. 13 is a detail perspective view of one of the guy tensioning devices. Figs. 14 and 15 are respectively vertical sectional views through the casing looking in opposite directions. Fig. 16 is a detail view on an enlarged scale of the cable guide.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, the derrick comprises a body and a mast slidably mounted thereon. The body consists of spaced convergently disposed side standards 14, having their intermediate portions connected by crossed braces 15, the lower ends of the standards being secured to a foot 16. A casing is carried by the upper portion of the standards, and includes spaced side walls 17 provided with downwardly inclined guide-ways or slots 18. The upper ends of the standards are connected by a guide sleeve or device 19.

A mast 20, slidably mounted in the upper portion of the derrick body, passes through the sleeve 19, and is slidable in the casing. A Windlass 21, journaled on the lower portion of the derrick body, has a cable 22 wrapped thereon, which cable extends upwardly within the body, and passes over a sheave 23 located in the upper portion of the casing, thence downwardly around a pulley 24 secured to the lower end of the mast, said cable having its upper end secured within the casing, as shown at 26 in Fig. 14. i

The lower end of the mast is provided with a notch 27 arranged to receive one of the pins 28 slidably mounted in the guide slots 18, and movable downwardly to a position beneath the lower end of the mast, when the same is raised. Rollers 29 are journaled in the casing on opposite sides of the mast, as shown in Figs. 9 and 10. With this construction, it will be evident that if the pins 28 are located in the'upper ends of the slots 18, they will be at one side of the mast, and said mast can be lowered. As many of the pins can be employed as desired. By turning the Windlass 21, however, the mast will be elevated, and when its lower end passes above either set of slots, the pins 28 therein will drop to a position beneath and in the path of movement of the mast. Therefore, if the mast is lowered, the pins will be received in the notch 27 and will support the mast.

The pins 28 are connected by clips 28 to the ends of a cable having stretches 29 that pass over the pulleys 30 suitably journaled on the frame. The stretches 29 of the cable extend downwardly along one of the side beams 14, and said cable passes around a roller 31 secured to the upper end of a weight 32 that is slidably mounted in the guide pocket 33*.

Eyes 34 are carried by the stretches 29 of the cable, and are arranged to be engaged with a hook 35 secured to the side beam above said eyes. It will be evident that if both eyes 34 are disengaged from the hook 35, the weight 32 will maintain the pins 28 in the upper end of the slots 18. If, however, one of the eyes 34 is engaged with the hook, the stretch of the cable that is connected to said eye will be sufiiciently slackened to permit the pin to drop into the lower end of its set of slots. Thus either or both of the pins may be held in the upper ends of the slots during the raising and lowering of the mast, and if it is desired to lower the mast, it is only necessary to disengage the eyes from the hook so that when the mast is raised slightly, the pin will be automatically drawn from its position beneath the same to the upper ends of the slots, and said mast can be lowered.

For the purpose of holding the derrick in erect position, suitable guy cables 30 are connected to the upper end of the mast, and are secured by suitable means on different sides of the derrick. Another guy cable 31, also secured to the upper end of the mast, extends downwardly at an inclination, and has its lower end wrapped upon a drum 32 journaled in a frame 33. This frame has a link 34 at one end arranged to engage with a hook 35. The hook 35 is provided with an opening 36 adapted to engage a holding device, as 37. Brace bars 38 have their upper ends hinged, as shown at 39, to the free ends of links 40, which links are hinged, as shown at 41, to the lower end of the derrick body.

A Windlass 42, journaled on the lower portion of the body, has the end portions of a cable 43 wrapped thereon. This cable has spaced stretches passing up over pulleys 44, thence about guide sheaves 45 on the standards 14 around other sheaves 46 on the outer ends of the links, and about pulleys 47. With this arrangement, it will be evident that by turning the windlass 42, the links 40 will be drawn towards the derrick, while the braces 38 will be free to swing. When said links 40 are against the derrick therefore, the braces 38 may be disposed at different inclinations thereto in order to reinforce the lower portion or body of the derrick.

Journaled on the lower portion of the body beneath the windlasses 21 and 42 is a hoisting drum 48, and the hoisting cable 49, wrapped upon the drum, extends over a crown pulley on the upper end of the mast, while its free end is arranged to be attached to the parts to be lifted. One end of the drum shaft 51 projects beyond one side of the derrick, and maybe provided with a handle crank 52, and a ratchet wheel 53, a dog 54 cooperating with the ratchet wheel. Actuating spools 55, form a part of the drum and have a cable 56 wrapped from one to the other, said cable being adapted to be connected to the draft animals or other means for rotating the drum. Associated with the spools 55 is a cable guide comprising a frame 55 having guideways 56 therein, communication between these guideways being controlled by a swinging gate 57 The other end of the shaft 51 to that carrying the crank 52, projects beyond the opposite side of the derrick, and a spool 57, that can be removed and reversed, is mounted against rotation thereon.

A cable 58, wrapped upon the spool 57, passes around a sheave 59, secured to the upper end of the mast 20, and is connected to a counterbalancing weight 60, slidably mounted, as shown at 61 upon the guy 31. The cable 58 passes over a guide roller or wheel 62, journaled on an arm 63 that extends from one side of the upper end of the derrick body. A very simple and effective brake is employed for the drum. As shown more particularly in Figs. 6 and 12, a single band 64 surrounds a brake wheel 65, one end of the band being fastened, as shown at 66 to the foot of the derrick, the other end being engaged with a crank 67, secured to an actuating lever 68. By operating the lever 68, the band can be loosened or tightened, as desired, and when loose, will support itself entirely free of the brake wheel 65.

The means for transporting the derrick consists of a vehicle 69 of any suitable character, having mounted on its rear end a turntable 70. The turntable consists of a suitable boxing held upon the vehicle by a pivot bolt 71. Arms 72 are pivoted to opposite inner sides of the boxing, and in these arms, a roller 73 is journaled. A crank shaft 74 is journaled in the turntable, and the crank 75 thereof is arranged to engage the arms 72. One end of the crank shaft projects through the turntable or boxing, and has an offset handle 76. By turning this handle, it will be evident that the roller 73 can thus be raised and lowered. A Windlass 76 is journaled in the boxing or turntable, and cables 77, wrapped upon this Windlass, pass through openings 78 in one side feature in this type of structure.

of the boxing, and are arranged to be detachably secured to the lower end of the derrick body by being tied thereto, or by any other well known method. It will be observed that the ends of the Windlass shaft 76 project beyond opposite sides of the turntable, as shown at 79, and one of these ends is square, as illustrated at to receive a handle crank.

The operation of this structure is substantially as follows: Assuming that the derrick is loaded upon the vehicle, as shown in Fig. 1, it will be evident that it may be transported from place to place. In this connection, it will be observed that the heavier end is located at the front end of the vehicle, an important When it is desired to erect the derrick, the vehicle is driven alongside of the desired position. The crank shaft 74 is then operated to raise the roller, and the derrick is moved thereon until it is properly balanced. The turntable is turned until the foot of the derrick is in proper position, after which the derrick is lowered from the vehicle by means of the Windlass 76 and cables 77. The free ends of the braces 38 are then engaged with the projecting ends 79 of the windlass shaft, whereupon the parts will be as illustrated in Fig. 2. The Windlass 42 is then rotated, and as this winds up the cable 43, as already described, therefore and by refer ence to Fig. 2, it will be evident that the derrick will be drawn by the cable towards the hinged ends 29 of the brace bars 38 and links 40, and this will effect the elevation of the derrick body to a substantially vertical position. The mast is then raised to the desired height by rotating the Windlass 21 which draws down the cable 22, thus elevating said mast, the guys are fastened, the braces 38 are detached from the vehicle, and arranged as shown in Fig. 6, thereupon the derrick is in position to be operated. By the reversal of the above described operation, the derrick can be again loaded on to the vehicle.

It will be evident therefore that the apparatus can be readily transported and erected. Experience has demonstrated that it is thoroughly efficient in its work.

The utility of the weight 60 will be clear by reference to Fig. 7. For instance if it is desired to lower a pump red as 49 the cable 49 is attached to the upper end of one of the pump rod sections 49, and the weight 60 will be sufiicient to elevate said section, as illustrated in Fig. 7. The section is then connected to the other section in the well, and their combined weight will be sufficient to raise the weight 60. As a result, the end of the cable will be lowered, and can be readily engaged with another pump rod section. The weight 60 then reacts to again elevate the next section so engaged.

The employment of the gate 57 is important. As already stated, the draft cable 56 is wound upon both the larger and smaller drums and passes from one to the other. In placing it upon these drums it is first wound on the smaller and thence passes over the rim between the drums and is wound upon the larger. In passing it the gate is held open. When the draft animals are connected to the cable and unwind it, they will of course first unwind it from the larger drum and consequently will have the benefit of the leverage thereof. After the cable has unwrapped from the larger drum it will pass over the rim between the two,

and the portion that is upon the smaller drum will unwrap. As it thus passes it will swing the gate out wardly and pass from one portion of the guide to the other. As a result, the animals do not have to travel as far as it a single drum of large diameter were employed, and it will be evident that any number of these drums of different diameters may be used.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
